This is my latest foray into imaging. It's been four long months, as weather here in NE Ohio simply hasn't been conducive to imaging, and my only imaging rig comes c/o of my local astronomy club's observatory.
It's not a fully apochromatic scope (notice the color bloat around the stars), but our 6" f/8 1980s-era AP triplet is good enough for what I'm trying to do.
I have an intervalometer, but I didn't use it, so I kept each sub at 30-sec. Unlike previous attempts at such exposure times (where I kept the ISO high to compensate), I dropped the ISO to 400 in the hopes of preserving a large amount of dynamic range to bring out the fainter nebulosity without blowing out the Trapezium/core region. I still ended up with a luminosity curve as contorted as a Tim Wakefield knuckleball on a blustery day, but I was able to preserve some of the "visual appearance" of the core region without totally blowing it out.
I'm still learning how to process. This is where I know the game's won and lost to a great degree. I only have DSS for stacking and GIMP 2.10 and Canon DPP for processing.
This is 34 light frames of 30-sec @ ISO 400, along with 20 dark frames, 20 bias frames and 10 flats.
